POWER-TRANSMITTING D'EVICE.

SPECIFICATION forming part of Letters Patent No. 778,405, dated December 27, 1904.

I Appnceeen nea Mey 25,1904. Vserial No. 209,692.

To all whom, t may concern:

Be it known that I, IsIDon DEiI'IsoH, a citi-` zen of the United States of America, residing at Montreal, inthedistrict of Montreal, in

the Province of Quebec, Canada,have invented certain new and useful Improvements In Power-Transmitting Devices, of which the` following is a specification.

My invention relates to improvements in IO power-transmitting devices; and the object of the invention is to devise an arrangement of parts which shall be compact and cheap to manufacture and at the same time of durable construction and whereby the parts are easy I5 of access and the eifect of any sudden jolting or jarring provided for; and it consists, es-r sentially, of agear-wheel secured to a rotatable axle, a strap encircling said axlel havinga v e flange extending therefrom and encompassing 2O said Wheel and a bearing projecting from one side thereof, -a pinion journaled on said bearing, and an arm secured to the strap and flexibly connected to a fixed support, the various parts being constructed and arranged in detail as hereinafter more particularly described.

Figure 1 is alongitudinal view of a' portion of an axle, showing my device in section mounted thereon. Fig. 2 is a cross-sectional view of an axle, showing my device partially 3C in section mounted thereon. Fig. 3 is aplan View of my device as applied to a railway-car. Fig. Asis an enlarged perspective detail of the flexible connection to the fixed support. Fig. 5 is a detail sectional view, on an enlarged scale, of the universal joint.

Like characters of reference indicate corresponding parts in each figure.

a is the axle, preferably tapered toward the center from each side, ascustomary in the formingof railway-car-wheel axles.

is the gear-wheel, preferably of the bevel type' of gear and split in two sections, though for convenience the parts will be considered as integral throughout the following description. The gear-wheel b is mounted on the axle a and rotates therewith.

c is a sleeve, preferably forming part with the gear-wheel and extending from the hub on the front side of the said wheel and surrounding the axle a.

0l is a journal formed by the annular raised 'portion on the sleeve c.

e is a strap having an internal bearing f, in which the journal Z turns. e

g is an annular flange from the strane, extending over theface of the gear-wheel and reaching around the edge to the rear thereof and having the turned extremity t.

2' is a cover surrounding the axle a, having a felt packing jabuttingthe axle. The cover t' is secured to Ythe extremity /t of the annular flange g and forms therewith a complete casing for the gear-wheel 7c is a circular opening from done side of the packingm, secured to the bell-shaped casing Z..

The oil-chamber contained in the casing-r has suitable `means of communication with the journal of the pinion-bearing and has a removable cover t.

u is a universal joint incased and secured to the removable cover t. o is a shaft secured to the other side of the universal joint. As shown in Fig. 5, an enlargedV ball-shaped head is formed at the end of the shaft o, through a slot in which head extends abar or bushing u. A pin u2, extending through said bushing and suitable apertures in the casing for the head formed on the shaft c, has its ends secured to a projection from the removable cover t. It

will be thus seen that the shaft, joint, and

cover t may be removed without disturbing the pinion, and this much facilitates matters in adjusting or repairing.

w is a rigid arm projecting from the Bange g, having the enlarged end m and an orifice y therethrough.

z is a stud inserted in the orifice y and fixedly secured therein. The stud e projects upwardly into a fixed supporting-bar 2 through the opening 3. The opening 3 is suficiently large to allow for any possible movement of the strap e incident to the jarring and jolting of the axle according to the circumstances under which the device is operating.

` 4 is a shoe straddling the supporting-bar 2 over the opening 8, having its downwardlyextending lugs `5 abutting the edges of said bar and having a central opening 6 therethrough. l

7 represents rods passing' under the supporting-bar 2 and fixedly secured to the lugs 5.

8 represents rigid pins projecting outwardly from each lug 5 and having the nuts 9 and washers lO at the ends thereof.

11 is a shoe straddling the supporting-bar 2' and abutting the same within the opening 6 in the shoe 4.

12 is a central orifice corresponding to the stud e, on which it fits.

13 represents lugs on the shoe 11, having orifices th'rough which the rigid pins 8 extend.

14 represents spiral springs encircling the rigid pins 8 between the washers 10 and the lugs 13 and act as cushions in any movement across the bar 2 on the shoe 11 and in consequence the stud z.

It will be seen from the foregoing description that at every movement of the axle the pinion and gear-wheel both assume the same relative position and also that any turning movement of the strap itself on the axle will be fully accounted for in the cushioning of the su pporting-stud e.

It is necessary in this device to have the supporting-stud fiexibly connected to the fixed support to permit of a limited movement of the strap and pinion in any direction. rherefore while, as aforesaid, it is most essential to have the most regular motion of the strap and pinion cushioned this must not be done Without having the parts capable of allowing movement in other directions. This particular arrangement of shoes will serve the purpose required, as the shoe 4 is stationary in any movement of the stud laterally tothe bar, while the said shoe has free movement longitudinally with the bar. The shoe 11, however, provides the fiexibility necessary laterally with the bar 2, as the stud at every movement of the strap circumferentially carries the said shoe with it and compresses either one or the other of the spiral springs. In

the movement of the stud longitudinally with the bar the shoe 11 will of course carry the shoe 4 therewith back and forth.

15 is an oil-reservoir formed in the flange g and having the inlet-opening 16 thereto from the outside of said flange and a suitable plug 17 closing said inlet.

18 is a wick-chamber formed in the flange g in proximity to thev4 oil-reservoir 15 and communicating with the journal u. 1S) isa plug closing the inlet to said wick-chamber.

2O is a channel formed in the flange f/ between the oil-reservoir 15 and the wick-chamber 18. 21 is a wick filling said wich-chamber 18.

rIhe reservoir is filled through the inletopening 16 and securely closed with the plug 17. The oil then passes through the channel 2O to the wick Q1, which becomes thoroughly saturated to where it abuts the rotating journal.

One of the uses to which thc power-transmitting device may be applied and to which it is particularly adaptable is that of transmitting power from the axle of a railway-car -to a dynamo located elsewhere on the car.

The difficulties incident in providing a transmission of this class are many and are chiefly caused by the tremendous jarring, jolting, and pounding which the truck of a railwaycar undergoes even on the very best road-bed.

It has always been considered diflicult lo devise a machine in which the parts would be so closely identified one with the other as te lessen the chances of some of the parts being either shaken off or thrown out of adjustment. In the present application l have provided a strap which is a considerable mass of metal closely identified with the axleand with the other parts, and not only does it support the pinion operated by the gear, but also has extending therefrom the principal part to form the casing. The other salient features besides the support already emphasized are the lubricating means for the internal hearing in the strap. All these features combined are essential to complete the proper working mechanism.

The strap and fiange herein described are shown in two sections in the drawings; but in the description this has not been explained,

as such construction is altogether a matter of convenience, according to the uses to which this form of device may be applied.

That I claim as my invention isw 1. In a power-transmittiug device, the coinbination with a support and a car-wheel axle, of a gear-wheel secured to the said axle and rotating therewith, a strap encircling said axle having a fia-nge extending therefrom and encompassing said wheel, and a bearing projecting from one side thereof, a pinion journaled on said bearing, and an arm secured to the strap and flexibly connected to the said support, as and for the purpose specified.
